Welcome to the fourth discussion on the ‘Colours!‘. The topic is getting so exciting and I am very much enjoying it. I am sure you are enjoying the series too, aren’t you?

Before going ahead, let’s take a quick recap of the first three posts we talked earlier. In the first post, we talked about our relative sensory system, due to which we can see. In the second post we discussed how we ‘see’. How the light emitted from the source gets converted into a brain signal. And further in the third post we met Mr. Light, talked how the ‘Electro-Magnetic Radiations’ of different wavelengths are ‘seen’ as different colours to us. Now today, we will be taking the topic ahead.

So we now know that, our eyes has three types of ‘Cone’ cells that works as receptors of three wavelength rays. These three wavelengths are seen as ‘Red‘, ‘Green‘, and ‘Blueish‘ in colour. In our eye retina, the count of such cones is about 2,50,000. Continue reading →

Since last two posts, we have established a good tempo and talking about Colours! Right? Yesterday, I was compiling all the notes for this post and was sorting topics. And while doing that, I was sort of thinking to ask my doubts to some one who can answer me well. While thinking about that I started dreaming of a meeting with such a one. I immediately called him and asked for his appointment and to my surprise he agreed. And you know what? Today, We have that very spacial guest with us.

‘Mr. Light’ himself. Yes The Great Mr. LIGHT HIMSELF! Ta Da!

Me: Hello Sir!

Mr. L: Hi Mahesh, how are you?

Me: I’m Great! Its my pleasure to see you. And how do you do, sir!

Mr. L: Pretty straightforward. But Mahesh, I am afraid that I have very short time for discussion now. I have to go to my friends birthday. Her name is twinkle. In next 15 seconds I have to reach there. So ask it quickly.

Me: OK, OK. Sir. I will ask you as fast as possible! I was discussing with my friends about how do we ‘see’. Can you describe us, how do we humans see colours? We would love if, you will put some light on that.

Mr. L: OK Time’s up. I need to go now. I will talk with you later! Till then why don’t you google about that your self? Hmm?

Colours! What a great and beautiful topic to discuss about. I am feeling really joyful to announce that for next few days we will be talking about such a wonderful topic.

We all know the importance of colours. Colours play a very significant role in our day to day life. Colour is the basic and most primary form of our knowledge of the world that surrounds us. Because of the colours we percept or interpret our environment. Colours are the very alphabets of one of our most prominent senses, the vision. Sight is the most vital sensory system among the five. And with colours we ‘see’, we communicate, we interact, we learn and we do all our activities.

The topic ‘Colour‘ has got both, the scientific side as well as the creative. Of course we are more interested in the creative side, where Continue reading →

I am in process of updating my blog. In 2003 and 2004, my 2 articles on 3d computer graphics, were published in local Marathi news paper (called ‘सकाळ’). I received huge response and replies from readers. Few more articles are about to be published very soon. So, I am going to add several 3d Graphics related training material on the blog in conjunction with the paper articles, in next few months. The sequence and selection of the training topics, will be based on public and reader’s replies, comments and feedback.

Following is the English version of my first article, originally published in ‘Sakal’ Daily News paper, Pune, on 18 Nov 2003, in Marathi. The translation is done by my wife ‘Shruti’. I decided to post this English translation, after I received few responses from some readers and friends, asking for the same. Please leave your comments and suggestions.

Computer Graphics – 3d Animation

About the 3D animation sector of computer graphics, which has made huge economical and industrial revolution all over the world, and which has become a big source of knowledge and earnings, for many artists…

‘The lion king’, ‘Tarzan’, ‘Toy story’, ‘Tom & Jerry’, ‘The Mummy’, ‘Star Wars’, ‘Jurassic park’…. the list is end-less, it goes on and on. What was behind all these movies that influenced the audience so much? Just one thing and that was excellent efforts put forth by the artists. In above all the examples one thing that is common is CG (Computer graphics). Using this CG, impossible things are made possible. In today’s age of ‘IT’ this is one of the most powerful medium that has reached up to the common man. Off course, this technology is not used just for entertainment purpose, but also in the fields of education, engineering, internet, medical, advertisements, case-studies and game developments.

Following is my second article which was published in ‘Sakal’s Appointments supplement on Tue, 19th Nov 2004. (‘Sakal’ is a popular Marathi daily newspaper). I had a very huge response from readers of Sakal from Pune. (see also – the first article published in Nov 2003)
